BBC3/PUMA is target of miR-483-3p. A, putative binding site of miR-483-3p in PUMA 3′UTRs (miRBase Target Database). Asterisks, nucleotides substituted in miR-483-3p predicted target site to perform luciferase assay (GGAGT>AATTA). B, PUMA 3′UTRs regulate luciferase activity dependent on miR-483-3p in HEK293, HCT116, and HepG2 cell lines (WT, wild-type; MUT, mutant; P, P value). Firefly luciferase activity was normalized on Renilla luciferase activity of the cotransfected pRL-TK vector. C, Western blot analysis of PUMA after miR-483-3p transfection in HEK293 and HepG2 cell line; the α (23 kDa) and β (18 kDa) isoforms are indicated. Cells were collected after 48 h of miRNA transfection. D, Western blot analysis of PUMA in Wilms’ tumor samples (T) and matched normal tissues (N).
